Specification of Letters Patent.

Patented Jan. 26, 1909.

Application filed April 27, 1908. Serial No. 29,379.-

-the `following is a speciiication.

. My inventionV relates to metallic sectional shelving wherein the shelves extend from one partition to another and the sections are of a e th equal to the length of a shelf.

he present invention is closely related to the one shown and described in my co ending application filed April 27, 1908, erial No. 429,490. ln that application the rods which support the Vshelves are formed to interiit directly one with another, the interttingl ortions being screw threaded so that the ro s may be screwed together by merely screwin one into the other without the use of. an intermediate coupling element. In such construction however, one end of the rod must be of reduced diameter and this requires either machine work tocut away .a

ortion of the stock if a solid rod is used or the line 3-3ll`ig.l 2. Fig. 4 is a sectional view taken on the line `4-"T4`Fig. 3. Fig. 5

is a sectional view showing a cap screwholding the tie rodf'at the end of the shelving'.v

Fig. 6 is a perspective view of the referred form of stud. 7 is a logitu inal sectional view of the tie rod made from a solid piece of metal instead of from a hollow tube.

The 'structure comprises four" principal kinds of elements, to wit, the vertical partitions 10, the shelves 11 the tie rods 12 andthe cou ling studs 13. The partitions are preferab y stiffened by means 'of marginal 'stri s 14 which are enlar ed cylindrically an are otherwise especial constructed in the 'manner described an claimed in an application iiled'by me April 17, 1908, Serial 0.'427,693. The shelves 11 may be stilli extend through the drawmgs, f

sectional elevation ened by longitudinal` ilanges 15 although these form no part of the present invention. lt is desirable also that these shelves be further stiilened by means of flanges' 1'6 as shown in the copending application last referred to.

The tie rods 12 are alike at each end and are slightly shorter than the shelves so that when the rods are tightened the shelves will come to a bearing against the sides of the partitions for the urpose of holding the shelves in place and When a tubular tie rod is employed as shown in Figs. 2 to 5 it is desirable that the ends be thickened somewhat by forging or swaging. This affords suhcient material te receive the tyspl" without unduly weakening the art. en the parts are assembled, the stu s 13 artition 10 which is apertured to receive it as shown in Fig. 4,- one end of the stud l ingwithin the end of the rod on one side ol7 the partition and the other end of the stud lying within the corresponding rod on the opposite side of the` partition. The stud has a collar 17 formed v thereon preferably integral therewith and in most instances it is desirable to form a number of flat surfaces- 18 on said collar for receiving a wrench whereby the stud may 'be .function, to wit, thatI of' affording a bearin surface or'shoulder for contacting the side o the partition'.A j It is clear that when the parts are assembled in the manner shown arid described, and

the rods are screwed up tight, the structure'` will exhibit great rigidlty combined with sim licit of construction'. The tie rods will the shelves may lie ilatthereon throu hout `be ree o protuberances with the result that l the entire length of the rod. The ro s will v be interchangeable end for end, at least until after-the stud has been screwed home into one end as above 1nd1c'ated thus requiring onl one kind of threading tool for the rods.'

e screw threads upon the coupling all run inthe same direction with the result that the tightening of one rod upon the coupling tends to tighten the coupling into the com'- panion rod; L

Although the tubular form of tie rod is preferable on account of its smaller weight, a solid rod 19 such as is indicated in Fig. 7 may be substituted without altering the cooperative relationshi of the parts.

The shelving is finished ofi:` at the ends by screwing cap screws 20 into the ends of the rodsto hol the partitions in place in the manner indicated 1n Fig. 5.

What I claim as new, and desire to secure by Letters Patent, is:

1. In shelving, the combination of an upright artition, a shelf extending therefrom on eac side thereof, a tie rod beneath each shelf internally threaded at the end, an externally threaded coupling member pene tratin said artition and adapted to screw into t e end) of 'said Arods for holding the structure together, and a collar upon said coupling member intermediate 'of the ends thereof, whereby the stud may be tightened into the end o f one of the tie rods previous to the erection ofthe structure. y

2. In shelving, the combination of an upright artition,a shelf extending therefrom on eac side thereof, a tie rod beneath each shelfinternally threaded at theend, and an externally threaded cou ling member penetrating said partition an being screw threadedwhereby it is adapted to'screw into the ends of said rods for holdingl the structure together, all the threads upon said coupling member running the same way so'that the tightening of one rod relatively to the cou ling member will also tend to tighten t e coupling member relatively to the other rod.

3. In sectional shelvin th'e combination of upright artitions, horlzontal shelves, tie

rods beneat said shelves, said tie rods beinginternally threaded at their ends and double ended screw studs penetrating the partition and adapted to screw into the roximate ends of the tie rods on opposite sldesvof the partition,.said shelves being longer than the rods whereby the shelves will be the first to cometo a bearing against the artitions and will consequently be heldiirm y in position when the rods are ti htened.

, In witness whereof, I have hereunto subscribed my name in the presence of' two witnesses. I BEVERLY L. WATERS.
